請依下文回答第 46 題至第 50 題： Words like stoical, practical and pragmatic are just a few words that could be applied to describe the stereotypicalSpaniards. The word “superstitious” usually is not on the list. However, once a year in the run-up to Christmas, it seemsthat their rationality goes out the window and many people change their patterns of behavior radically for just a fewweeks. To understand why, we first need to understand “the fat one.”“The fat one” refers to the 205-year-old Spanish Christmas Lottery, “El Gordo,” which is the biggest lottery in theworld in terms of the total prize money on offer. Its fund structure allows many more winners than other conventionallottery draws. This hugely popular lottery draw first took place in 1812 and has been held on December 22 every yearsince then, even continuing through the Spanish Civil War and both World Wars. Winning numbers are drawn by childrenfrom Madrid's San Ildefonso school, which was originally a home for orphans of civil servants. The pupils deliver theresults in a song by picking and singing out a lottery number from one big golden drum, and then its corresponding prizeamount from the other drum. On this date, the streets of Spain are silent as everyone watches the broadcast of the ElGordo lottery draw, a love affair which can take over three hours.There are many superstitions about the El Gordo lottery tickets. Some people claim that rubbing your lottery ticketagainst a pregnant woman’s belly, a bald man’s head or a cat’s back will make it a winner. In the northwestern region ofGalicia, lottery players hang their tickets on horseshoes. In other regions, people tuck their ticket next to a figure of theVirgin Mary. Some Spaniards believe that the key to good luck comes in the form of an actual key, so they carry an oldiron key in their pocket with the lottery ticket.
